I don't understand the hostility of other comments. I had a quick look on the code and it is essentially IRC+Kiwi but in Rust, or a Matrix public chat room without signups. All chats are in memory and not saved to disk or DB. There is username but you can claim who you wants to be. The dependencies looks sane and reputable. I do saw there is a WebSocket lib being used but not found in code. However I don't code in Rust nor I understand WS well so take a grain of salt here.

It does provide anonymity, but not privacy or confidentiality. It does what it claims.
